Cryptocurrency is a digital currency which, in the opinion of some people, is the currency for the future, I believe it is because it has been proven that today everything is digital and online. And there are some shops or service providers that already accept Cryptocurrency as their payment tool. But in my opinion not all Crypto will be able to survive in the current Crypto coin competition, only those who have a large community such as Bitcoin and Ethereum and other large coins are able to survive and will function as a digital currency of the Future.
